I have an OpenStack setup in virtual environment on CentOS 7.
The baremetal has *nested KVM* enabled and 1 compute node as a VM.
Inside the compute node I have multiple VMs running.
After about every 3 days the VMs get inaccessible and the compute node reports high CPU usage. The qemu–kvm process for each VM inside the compute node reports full CPU usage.
Please help me with some hints to debug this issue.
